Impact of malnutrition in patients with severe heart failure.

AIM: The role of malnutrition among patients with severe heart failure (HF) is not well established. We evaluated the incidence, predictors, and prognostic impact of malnutrition in patients with severe HF. METHODS AND RESULTS: Nutritional status was measured using the geriatric nutritional risk index (GNRI), based on body weight, height and serum albumin concentration, with malnutrition defined as GNRI ≤98. It was assessed in consecutive patients with severe HF, defined by at least one high-risk 'I NEED HELP' marker, enrolled at four Italian centres between January 2020 and November 2021. The primary endpoint was all-cause mortality. A total of 510 patients with data regarding nutritional status were included in the study (mean age 74 ± 12 years, 66.5% male). Among them, 179 (35.1%) had GNRI ≤98 (malnutrition). At multivariable logistic regression, lower body mass index (BMI) and higher levels of natriuretic peptides (B-type natriuretic peptide [BNP] > median value [685 pg/ml] or N-terminal proBNP > median value [5775 pg/ml]) were independently associated with a higher likelihood of malnutrition. Estimated rates of all-cause death at 1 year were 22.4% and 41.1% in patients without and with malnutrition, respectively (log-rank p < 0.001). The impact of malnutrition on all-cause mortality was confirmed after multivariable adjustment for relevant covariates (adjusted hazard ratio 2.03, 95% confidence interval 1.43-2.89, p < 0.001). CONCLUSION: In a contemporary, real-world, multicentre cohort of patients with severe HF, malnutrition (defined as GNRI ≤98) was common and independently associated with an increased risk of mortality. Lower BMI and higher natriuretic peptides were identified as predictors of malnutrition in these patients.

Clinical burden and predictors of non-cardiovascular mortality and morbidity in advanced heart failure.

BACKGROUND: The changing demographic of heart failure (HF) increases the exposure to non-cardiovascular (non-CV) events. We investigated the distribution of non-CV mortality/morbidity and the characteristics associated with higher risk of non-CV events in patients with advanced HF. METHODS: Patients from the HELP-HF registry were stratified according to the number of 2018 HFA-ESC criteria for advanced HF. Endpoints were non-CV mortality and non-CV hospitalization. Competing risk analyses were performed assessing the association between HFA-ESC criteria and study outcomes and the additional predictors of non-CV endpoints. RESULTS: One thousand one hundred and forty-nine patients were included (median age 77 years-IQR 69-83). At 6, 12, 18 and 22 months, cumulative incidence of CV vs non-CV mortality was 13% vs 5%, 17% vs 8%, 20% vs 12%, 23% vs 12%, and of CV vs non-CV hospitalization was 26% vs 11%, 38% vs 17%, 45% vs 20%, 50% vs 21%. HFA-ESC criteria were associated with increasing adjusted risk of CV death, whereas no association was observed for CV hospitalization, non-CV death and non-CV hospitalization. Predictors of non-CV death were age, chronic obstructive pulmonary disease, dementia, preserved ejection fraction, >1 HF hospitalization and hemoglobin. CONCLUSIONS: Patients with advanced HF are exposed to high, even though not predominant, burden of non-CV outcomes. HFA-ESC criteria aid to stratify the risk of CV death, but are not associated with lower competing risk of non-CV outcomes. Alternative factors can be useful to define the patients with advanced HF at risk of non-CV events in order to better select patients for treatments specifically reducing CV risk.

[SICI-GISE/SICOA Consensus document: Clinical follow-up of patients after acute coronary syndrome or percutaneous coronary intervention]. / Documento di consenso SICI-GISE/SICOA: La gestione del follow-up del paziente dopo sindrome coronarica acuta e/o angioplastica coronarica.

In the last decades, advances in percutaneous coronary intervention (PCI) strategies have significantly reduced the risk of procedural complications and in-hospital mortality of patients with acute coronary syndromes (ACS), thus increasing the population of stable post-ACS patients. This novel epidemiological scenario emphasizes the importance of implementing secondary preventive and follow-up strategies. The follow-up of patients after ACS or elective PCI should be based on common pathways and on the close collaboration between hospital cardiologists and primary care physicians. However, the follow-up strategies of these patients are still poorly standardized. This SICI-GISE/SICOA consensus document was conceived as a proposal for the long-term management of post-ACS or post-PCI patients based on their individual residual risk of cardiovascular adverse events. We defined five patient risk classes and five follow-up strategies including medical visits and examinations according to a specific time schedule. We also provided a short guidance for the selection of the appropriate imaging technique for the assessment of left ventricular ejection fraction and of non-invasive anatomical or functional tests for the detection of obstructive coronary artery disease. Physical and pharmacological stress echocardiography was identified as the first-line imaging technique in most of cases, while cardiovascular magnetic resonance should be preferred when an accurate evaluation of left ventricular ejection fraction is needed. The standardization of the follow-up pathways of patients with a history of ACS or elective PCI, shared between hospital doctors and primary care physicians, could result in a more cost-effective use of resources and potentially improve patient's long-term outcome.

Cardiac electrical instability in Erdheim-Chester disease: a case report.

Erdheim-Chester disease (ECD) is a rare multisystemic disorder of non-Langerhans histiocytic cells with a pleomorphic clinical presentation. It affects bones, skin, central nervous system, pituitary gland, ocular tissue, kidneys and perirenal tissue and lungs. Cardiac involvement presents usually with pericardial effusion and right atrial masses, but rarely with conduction system infiltration and subsequent arrhythmic events. Following the discovery of mutations of activating signaling kinase proteins (BRAF, MEK, ALK), the therapeutic landscape has changed to a more precise targeted treatment. Currently vemurafenib is approved for patient with end-organ dysfunction and BRAF-V600E mutation and the prognosis has dramatically improved. Here we present a case of ECD with electrical instability as main clinically relevant manifestation of cardiac involvement.

Bedside intra-aortic balloon pump insertion in cardiac intensive care unit: A single-center experience.

BACKGROUND: In contemporary Cardiac Intensive Care Unit (CICU), bedside intra-aortic balloon pump (IABP) insertion under echocardiographic guidance may be an attractive option for selected patients with cardiogenic shock (CS). Currently available data on this approach are limited. AIM: This study aimed to assess the feasibility and safety of bedside IABP insertion, as compared to fluoroscopic-guided insertion in the Catheterization Laboratory (CathLab), and to describe the clinical features of patients receiving bedside IABP insertion using a standardized technique in real-world CICU practice. METHODS: We prospectively evaluated all patients admitted the CICU who received transfemoral IABP between June 2020 and October 2021. The overall study cohort was divided according to implant strategy in bedside and CathLab groups. The primary outcome was correct radiographic IABP positioning at the first bedside chest X-ray obtained after insertion. Secondary outcomes included IABP-related complications. RESULTS: Among 115 patients, bedside IABP insertion was performed in 35 (30.4%) cases, mainly presenting with CS-related to acute decompensated heart failure (ADHF) (68.6 vs 33.8%; p < 0.001), with lower LVEF, higher proportion of right ventricular involvement and higher need of inotropes/vasopressors, compared to those receiving CathLab insertion. Bedside IABP insertion resulted feasible and safe, with similar rates of correct IABP positioning (82.9 vs. 82.5%; p = 0.963) and IABP-related major vascular complications (5.7 vs. 5.0%; p = 0.874), as compared to CathLab positioning. CONCLUSION: This study suggests the feasibility and safety of bedside IABP insertion, which could be of relevant interest in patients with ADHF-related CS who may not need coronary angiography or other urgent CathLab procedures.

Right ventricular endomyocardial biopsy in patients with cardiac magnetic resonance showing left ventricular myocarditis.

AIMS: The aim of this study was to evaluate the sensitivity of right ventricular endomyocardial biopsy (EMB) in myocarditis patients with cardiac magnetic resonance (CMR) and electroanatomical mapping (EAM) showing left ventricular abnormalities. METHODS: We performed right ventricular EMB in 144 consecutive patients (66% men, age 43 ±â€Š15 years) with acute symptoms and CMR-proved diagnosis of left ventricular myocarditis. Right ventricular EMB sensitivity has been evaluated in patients with different localization and extension of abnormal substrate at both CMR and -- when performed -- EAM. Abnormal substrate was defined, respectively, by late gadolinium enhancement (LGE) and low-voltage areas (LVAs). RESULTS: Globally, right ventricular EMB sensitivity was 87.5%. EMB-negative cases had significantly smaller fragment sizes (cumulative area 2.8 ±â€Š1.7 vs. 3.8 ±â€Š1.8 mm2, P = 0.023), and lower LGE surface extension (24.7 ±â€Š14.2 vs. 38.5 ±â€Š20.2%, P = 0.006) and transmurality (32.0 ±â€Š26.1 vs. 49.3 ±â€Š22.6, P = 0.003). Right ventricular EMB sensitivity in patients with LGE involving both right ventricular and interventricular septum (IVS), isolated right ventricular or IVS, and remote left ventricular areas (n = 10, 49 and 67 cases) was 83.3, 84.4 and 90.5%, respectively (P = 0.522). Overall, 34 patients (23.6%) underwent EAM. On the basis of EAM, right ventricular EMB sensitivity was 85.3%: in detail, it was 50.0, 88.2 and 86.7% in patients with both right ventricular and IVS, isolated right ventricular/IVS and distant left ventricular involvement (n = 2, 17 and 15, respectively, P > 0.05). Sample size area was the only factor associated with right ventricular EMB sensitivity (hazard ratio = 1.6/mm2, 95% confidence interval 1.1-2.4, P = 0.013). CONCLUSION: Right ventricular EMB is still an accurate technique to confirm diagnosis in patients with CMR-proved left ventricular myocarditis. In particular, provided there is an adequate sample size, its sensitivity is comparable among patients with heterogeneous LGE or LVA localization.

[Transcatheter aortic valve implantation for aortic regurgitation in patients with left ventricular assist device]. / Impianto transcatetere di valvola aortica per insufficienza aortica nei pazienti con assistenza ventricolare sinistra.

Aortic valve regurgitation is a not negligible complication of prolonged support with continuous-flow left ventricular assist device (LVAD) and is associated with recurrence of heart failure and reduced survival. Transcatheter aortic valve implantation has been described as a feasible option in this setting, usually with self-expanding prosthesis. Giving the absence of valvular calcification, a proper prosthesis oversizing should be guaranteed in order to achieve sufficient sealing and avoid prosthesis migration or paravalvular leak. Current self-expanding prosthesis may be too small to fit aortic annulus anatomies without calcification and with the need of significant oversize. We report the first case of 32 mm balloon expandable Myval prosthesis implantation in a patient with LVAD-related aortic regurgitation. Large balloon-expandable prosthesis can be considered when a significant oversize is needed.

Meta-Analysis Comparing P2Y12 Inhibitors in Acute Coronary Syndrome.

Dual antiplatelet therapy combining aspirin with a P2Y12-receptor inhibitor reduces atherothrombotic events following an acute coronary syndromes (ACS), but the relative merits of different P2Y12 inhibitors remain unclear, despite several recent large-scale trials. We performed a network meta-analysis, representing the largest evidence to date to inform P2Y12 inhibitor choice in patients with ACS. Fourteen studies were included, for a total population of 145,019 patients. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used in this systematic review. A network meta-analysis using a frequentist approach with surface under the cumulative ranking probability calculation was performed. Major adverse cardiovascular events (MACE), all-cause death, myocardial infarction (MI), definite stent thrombosis (ST) and major bleeding at 30-day and 1-year all-cause death and MI were the study endpoints. At 30-day, prasugrel was superior to both clopidogrel and ticagrelor in MACE, all-cause death and definite ST endpoints. Both prasugrel and ticagrelor were superior to clopidogrel in MI endpoint. Ticagrelor also reduced all-cause death compared with clopidogrel. Ticagrelor, prasugrel, and clopidogrel resulted equivalent in terms of the safety outcome of 30-day major bleeding. No significant difference was found among clopidogrel, prasugrel, and ticagrelor with respect to 1-year MACE outcome. Both prasugrel and ticagrelor reduced the occurrence of 1-year all-cause death compared with clopidogrel. Prasugrel reduced 1-year MI rate as compared with clopidogrel, while ticagrelor did not. At probability analyses, prasugrel ranked best in all 30-day and 1-year efficacy and safety endpoints. In conclusion, in this network meta-analysis, prasugrel showed the highest efficacy in reducing adverse outcomes in ACS patients and had the highest probability of being the best P2Y12 inhibitor to reduce hard adverse events both at 30-day and 1-year follow-up.

Impact of systemic immune-mediated diseases on clinical features and prognosis of patients with biopsy-proved myocarditis.

INTRODUCTION: Myocarditis has been described in association with many systemic immune-mediated diseases (SIDs). However, the role of SIDs in influencing clinical presentation and outcome of patients with a new diagnosis of biopsy-proved myocarditis, has never been investigated so far. METHODS: We enrolled 25 consecutive cases with biopsy-proved myocarditis in the context of SIDs, and controls with isolated myocarditis, matched 1:1 by age, gender, ethnicity and clinical presentation. All of the patients presented with acute symptoms, normal coronary arteries, and no previous history of myocarditis. Detailed diagnostic workup, including blood exams, echocardiogram, arrhythmia monitoring and cardiac magnetic resonance (CMR) were obtained at baseline and at defined time points, up to 12-month follow-up (FU). RESULTS: At presentation, patients with SIDs had more commonly inflammatory biomarkers elevation, signs of associated pericarditis, and replacement fibrosis at histology, as compared to controls (18 vs. 6, 20 vs. 12, and 21 vs. 11, respectively; all p < 0.05). The Lake Louise criteria at CMR were negative in 19 vs. 10 patients with and without underlying SIDs, respectively (p = 0.021). Baseline ECG, in-hospital arrhythmia telemonitoring and echocardiographic findings were not significantly different between groups (all p = n.s.). At 12-month FU, the composite major endpoint of cardiac death, end-stage heart failure or malignant ventricular arrhythmias was significantly more common in cases than in controls (7 vs. 1, respectively, p = 0.049). CONCLUSION: In patients with a new diagnosis of myocarditis, the presence of underlying SIDs is associated with distinct baseline clinical features and a significantly worse 1-year outcome.
